DETACHAZBLE CLOSURE.

Be it known that I, WILLIAM at Ashland, in the county of Boyd and State of Kentucky, have invented certain new and" useful. Improvements in Detachable Glosures, of which the following is a speci,

ceptacles but particularly to one adapted to be utilized in connection with paper boxes and the like, as. for example, thekind in received. 7

.Itis also the purpose of'this inventionto which breakfast foods terial arepackaged.

' One.- object of he invention is to provide a. closure which may be conveniently attached to: a paper or board box by making a suitable. openin in said box or the attachmentheingsucht at the. closure may be con veniently removed for attachment to another boxor receptacle.

Anotherobject of the invention is to- (re vide means whereby a cutting edge may orm' part of the closure to out an opening of a propriate size so that the closure may e provide means wherebygthatportion of the paper box'surrounding theiopening maybe clamped between two members carrie by the closure so that the liability of the'closure becoming accidentally detached will be avoided. I p

In" the drawings illustrating one embodiment of my invention, Figure 1- is a vertical longitudinal sectional view through the box or receptacle to which a closure constructed in accordance with my invention is applied. Fig. 2 is a plan view of a clampingring. Fig. 3 is a slmilar view of the throat member. Fig. 4 is a fragmentary plan view of a portion ofthe receptacle to receive the closure and Fig. 5 'is a fragmentary sectional view of the throat member illustrating the cutting edge.

merals of reference 1-designates a throat member provided with spiral corrugations or threads. on the exterior thereof. At the base of the-throat member 1 is a circumfer ential flange 2 having a notch'or slit 3 therein which may be formed by cuttingout a Specification of Letters Patent.

Arman-- son, a citizen of the United States, residingand similar ma-k a tine or projection 4 having acuttin ed e,

the purpose of which will be specifica lyescribed hereinafter.

5 designates a clamping ring .or collar having corrugations corresponding tq those on throat 1 and adapted to enga e the threads thereof whereby said ring may e screwed on tosaid throat I. The ring 5 is provided with a circumferential flange 6- which when inits clamped position Wlll be approximately parallel with the. flange 2 on the throat 1. For convenience in screwingthe. ring 5 .onto and unscrewing it from the throat I, I may.

provide projections 7 and 8 in the: flan e 6.

These projections may be struck up mm the flange 6, as shown in ,Fig'. 2.

9 is a cap or cover ada ted. to be screwed Patented Jan. 18-, 1910. Application filed January 27, 1909. Serial No. 474,604. I

onto the throat 1 to exclu e air and moisture from the receptacle.

The receptacle. 10 is shown in. Fig, 4.. as being provided with anannular' openlng. 115 the edge-surrounding the opening 11 being" inserted by the transverse slit 12. The diamleter of the flange 6 is such that it will overlap the notch 12in the receptacle 10, as will be clear by reference to Figs; 1 and. 2.

As heretofore stated; the paper box or. re-

ceptacle will ordinarily be.. sealed. and irrstead; of breaking the; sealin the usualfman: ner, the operator may press the tine a through the wall of package at any convenient place and by'jr'otating the throat a circle ma be scribed upon the package or a dlsk entirelycut therefrom of a size approximately the size of the'throat but the diameter'ofwhich will be less than the diameter of the flange 2. A slit of appropriate length of the receptacle and one of the edges of the notch 3 may then be inserted through the slit 12 so that by turning the throat'me'mber the entire flange 2 may pass through said slit 12 and lie against the inner side of the wall of the receptacle 10. The clamping ring may I then be screwed upon the throat so that the Referring now to the drawings by nu-- tion the closure will be securely held until itis necessary or desirable to remove it.

The cap 9 may be applled and removed without in any way affecting the attachment of the closure to the receptacle.- If it is found desirable, grooves or recesses 13 and as shown at 12, may'then be cut in the wall 14 maybe formed in the flanges 6 and 2 respectively so as to crimp the wall of the receptacle when the two flanges are in clamping position and so as to prevent slipping of the flanges on the receptacle wall when the ring 5 is screwed into position. Ordinarily, however, these grooves or recesses may be dispensed with.

It is obvious that the closure may be readily attached to and detached from the box and that it'may be repeatedly used without affecting-its efliciency.

Having thus described my invention, what I claim as new therein, and desire to secure by Letters Patent is 1. The combination witha receptacle, of

a detachable closure therefor, comprising a throat, means carried by the throat for perforating and effecting its application to the receptacle, and means for clamping the throat to said receptacle.

2. The .combination with a receptacle, of

i Y a-detachable closure therefor, comprising a throat having a lateral flange, means carried by :the throat for perforating and effecting the application of the flange within the receptacle, means for clamping the'throat in applied position, and-a cap to fiton said throat.

3. The combination with a receptacle, of a detachable closure therefor, comprising a throat, a lateral flange carried by the throat flange to the receptacle.

having a slit adapted to permit the insertion of the flange within a receptacle, and means to secure the closure to the receptacle.

5. In a detachable closure for receptacles, a throat member having a flange, means carried by the closure proper for perforating a receptacle and inserting the flange therein, and a collar movable over the throat and adapted to clamp said closure to the receptac e. Y

6. In a detachable closure for receptacles, a. throat member having screw threads, a notched flange on said throat adapted to permit the application of the closure to a receptacle, and a clampingcollar threaded on said throat and adapted to secure the closure in position.

7. A detachable closure for comprising a throat having a lateral flange with a cutting edge struck therefrom, and adapted to 'cut in a receptacle an opening of less diameter than the flange, said flange adapted to be inserted in said opening, and

means for securingflthe closure in applied position. i

8. A detachable closure for receptacles comprising a throat, a flange on the throat having means whereby said flange may be inserted within an opening in a receptacle of less diameter than said flange, and a clamping member to fit over the throat and receptacles provided with a flange to overlap the flange to be inserted.

The foregoing specification signed at Ashland, Ky., this fifteenth day of December, 1908.
